QuantLib Python installation on windows machine


I am trying to install QuantLib Python in my windows machine using the instructions given in
I did the following:

I downloaded QuantLib-1.10, SWIG and installed boost.

I built the QuantLib-1.10 in my windows 8 machine using Visual Studio 2017 comunity edition. Succefully produced QuantLib-vc141-x64-mt.lib.

Then I did the following in the command window.

cd C:\local\QuantLib-SWIG-1.9\Python
  set QL_DIR=C:\local\QuantLib-1.10
  set INCLUDE=C:\local\boost_1_64_0

and then
python setup.py build

It failed because it was looking for QuantLib-vc140-x64-mt.lib. I changed the name  QuantLib-vc141-x64-mt.lib to QuantLib-vc140-x64-mt.lib. It accepted it and built it.

Then I tried python setup.py test.

It failed giving error messages given below.

What am I doing wrong?
Can someone help me.
